Water moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as Stevia alpina is susceptible to root rot. Ensure good drainage in pots and beds.

Reduce watering in cooler months, allowing the soil to dry out more between waterings.

Prune lightly in spring to shape the plant and encourage bushier growth. Remove any dead or damaged stems. Pinch back the tips of young plants to promote branching.

Heavy pruning is generally not required unless the plant becomes leggy or overgrown.

Propagate Stevia alpina through stem cuttings taken in spring or early summer. Dip the cut end in rooting hormone and plant in a well-draining, moist potting mix.

Keep the cuttings in a warm, humid environment until roots develop, usually within 4-6 weeks.

Repot Stevia alpina every 1-2 years, or when it becomes root-bound, preferably in spring. Choose a pot that is slightly larger than the current one and ensure it has drainage holes.

Use a well-draining potting mix to prevent waterlogging.
